Toyosatomimi no Miko continued to observe and plan, and tensions were ever rising. In 1856, the Second Opium War had broke out. Fed up with the West, Seiga went on to fight against the Anglo-French Forces. Once at the sight of the battle, she used her spell cards and managed to heavily destroy the invading armies. The Anglo-French Forces were shocked by the amount of power, but nevertheless tried to continue fighting. However, it was no use, and many of their troops and ships were destroyed by the Hermit. A year later, the opposing forces surrendered, and ended in a Chinese victory.
In 1858, more unequal treaties were introduced to both China and Japan. In the former, a few weeks before the Treaty of Aigun, Seiga went to fight against the Russians that threatened the local population with expulsion. Within hours, the Russo-Chinese War had erupted, and Russia ordered an invasion of China. However, they were quickly pushed back, and suffered major losses. The war lasted for five months, and ended with a Chinese Victory. As a result, Russia moved out of the Chinese lands in Manchuria, especially from the Amur areas, and the Treaty of Aigun was never introduced.
In the latter, Japan had signed five separate treaties from five different nations. Miko, after enough planning, begun to take a tour to the West, under a disguise. During her trip, she observed and studied their technology and sciences very carefully. After about seven years, she returned back into Japan, and seeing the continued rising tensions, went to meet with the Shogun and Emperor. Two years of discussion later, in 1867, Tokugawa Yoshinobu agreed to resign and give power to the Emperor. A few days later, the Shogunate was dissolved, and the Dajokan (Great Council of State) was established by Emperor Meiji, with some changes. Rapid industrialisation and modernisation also begun, with the aid of Miko, to compete and be on par with the Western Powers.
Later in 1876, after more talks between Miko and Meiji, the Emperor agreed to reform the government. The Dajokan was dissolved, and a year later, a constitution was written, turning the nation into a Constitutional Monarchy, and the Prime Minister office was established. The first elections took place a few weeks later, and lasted until the first month in 1878. Miko, being one of the candidates, won the elections and became the First Prime Minister of Japan, beating both Itō Hirobumi and Reimu Hakurei. Under her rule, Japan became even more prosperous and powerful.
Several months later, Miko went on to visit Korea, China, and Siam. During her trips, she met with the leaders of those nations and encouraged them to industrialise and strengthen themselves. With enough convincing, the Monarchs had agreed and a week later, a friendship trade treaty was signed between the four nations. After a short war from 1884 to 1885 between China and France over the control of Tonkin, Miko, Korea, China, and Siam came together and established the Association of Independent Asian Nations, a political, economic, and military organisation aimed to better cooperate with each another and also defend as one.
The organisation take part in their first conflict, at the Franco-Siamese War in 1893. The four came together and fought off the French, and within weeks after suffering heavy losses, France decided to end the war and withdraw from Siamese Laos. The organisation also took part in the Boxer Rebellion, intervening on the side of China against the Seven Nation Alliance (United Kingdom, Russia, France, USA, Germany, and Austria-Hungary) that also intervened. The conflict dragged on until 1902, when the Seven Nation Alliance decided to surrender and a treaty was signed. In it, the Alliance agreed to withdraw their missionaries, pay reparations, and establish a non-aggression pact.
Despite the victory, the Qing Dynasty continued to weaken slowly, soon giving way to the Xinhai Revolution in 1913. Upon the overthrow of the monarchy, the Republic of China was established. Worried of the situation in China, Miko, Korea, and Siam went to make sure the Western powers don't try to take advantage of the situation. After Yuan Shikai's unsuccessful attempt to establish himself as Emperor of China, and his death in 1916, China continued to fracture further and plunged into the Warlord Era. Once China was reunified in 1928, it descended into Civil War between the Kuomintang and the Communists.
During the Civil War, Kuomintang leader Chiang Kai-shek and Kaku Seiga looked for outside support, and asked Korea, Japan, and Siam for support. The governments quickly agreed, and begun to aid the Kuomintang in the Civil War. The Communists, met with much opposition, begun seeing quick losses, and by year 1934, were utterly defeated and the Communist Chinese Party leaders were executed. After the Civil War, China begun to repair itself with aid from its allies.
In later 1939, a War broke out in Europe. Once France and the Lowland Countries fell to Germany in 1940, the Association of Independent Asian Nations took note and entered the war on the Allied Side. The forces launched an invasion of French Vietnam and the Dutch East Indies to occupy them temporarily. Once the War in Europe ended, Miko called for the Western powers to begin the decolonisation in East, South-East, and South Asia. Not wanting to face war, the Colonial Empires reluctantly agreed to do so.
With the Cold War rising, and after a long meeting, Japan, Korea, China, and Siam planned out to fully unite into one nation. Negotiations were successful, and by 1955, the East Asian Federation was established. Miko became elected as President, while Chiang Kai-shek was elected as Vice-President, and Kaku Seiga was elected as Primer. With the combination of the Four Great Powers into one, their influence greatly expanded and strengthened throughout South and South East Asia. Tensions between the Three Superpowers and their respective blocs were quite tense as well and competed against one another.
By the 1990s, these tensions would die out and the Cold War came to an end. The Soviet Union had collapsed in 1992, and split into thirteen new nations. The USA and the East Asian Federation went to improve relations with each other, and both would remain superpowers.
Toyosatomimi no Miko remains President of the East Asian Federation to this day.

In this next timeline, is the finale of the First Season. As such, there are several points of divergence. It all starts in China, in year 587. Seiga Kaku is enjoying her time, and decides to visit Japan. Once there, she hears about the Battle of Shigisan taking place at the moment, and goes to check it out.
Meanwhile in South East Asia, the Khmer Empire, under rule of Byakuren Hijiri, was expanding greatly and remains undetected by Seiga for now...
